Description of Operation

Become familiar with these controls before operating the unit.

Auto (I)/Off (O) Switch: Turn this switch "Auto (I)" to provide automatic power to the pressure switch and "Off (O)" to remove power at the end of each use.

Pressure Switch: The pressure switch automatically starts the motor when the air tank pressure drops below the factory set "cut-in" pressure. It stops the motor when the air tank pressure reaches the factory set "cut-out" pres- sure.

Safety Valve: If the pressure switch does not shut off the air compressor at its "cut-out" pressure setting, the safety valve will protect against high pressure by "popping out" at its fac- tory set pressure (slightly higher than the pressure switch "cut-out" setting). Outlet Pressure Gauge: The outlet pressure gauge indicates the air pres- sure available at the outlet side of the regulator. This pressure is controlled by the regulator and is always less than or equal to the tank pressure. Tank Pressure Gauge: The tank pres- sure gauge indicates the reserve air pressure in the tank.

Regulator: Controls the air pressure shown on the outlet pressure gauge. Pull the knob out and turn clockwise to increase pressure and counterclock- wise to decrease pressure. When the desired pressure is reached push knob in to lock in place.

Universal Quick-Connect Body: The universal quick-connect body accepts the three most popular styles of quick- connect plugs: Industrial, automotive (Tru-flate), and ARO. One hand push- to-connect operation makes connec- tions simple and easy.

Drain Valve:
The drain valve is
located at the
base of the air	Drain
tank and is used	Valve
to drain conden-
sation at the end of each use.

Cooling System (not shown): This compressor contains an advanced design cooling system. At the heart of this cooling system is an engineered fan. It is perfectly normal for this fan to blow air through the vent holes in large amounts. You know that the cooling system is working when air is being expelled.
